12V source for testing Haldex pump 30783079 Topic is solved

Post by **erikv11** » Tue Dec 22, 2020 9:06 am

When applying 12V to test if this pump is operational while in the car ... can I just use a car battery or I read somewhere to use a small 12v battery source?

I just used a lead off the battery.

Thanks for the quick reply. I was able to test it tonight.

It's dead, Jim.

Make up a fused test lead for this for a battery probe. Your battery will push a couple of hundred amps on a short and that can be quite spectacular

10-15 amp should work for most anything, you can even just use female spades to push into a standard Volvo fuse then wrap with electrical tape to insulate.

Yeah I made up some test leads to easily hook to A spare battery I keep around and charged for jumps etc. Did not make an inline fuse I will add that in now for future tests. It was the amps I was worried about didn’t think about a short.

Always the right way the second time, the first time you short a battery to ground its memorable

I've got a little experience with learning the hard way too, just replacing my front end for the second time this year........this time with good parts!

Expensive/difficult/painful lessons are the easiest to remember.
